I believe it is. You say one of your problems is "we’re not doing well enough at engaging with people about our product". Perhaps I am part of the group you would like to engage, I'm not sure. I read a lot of Hacker News and I recognise your website, so I must have been to it before, but when I saw this post I thought "what's Gittip again?"
Honestly, I can't even figure out how to pronounce Gittip. Is it git-tip? When I try to say it that way I get tongue-tied over the double-t. Gid'ip, with a kind of southern drawl? If I was trying to tell someone about it I would say "there's this neat crowdfunding patronage type site called g-i-t-t-i-p". Or just type it into their computer/phone. That's not where you want to be. Names are what we hang ideas on, and I can't even hang a sound on yours.
Speaking of ideas, I feel like there is a fundamental disconnect between the passion and grandiosity of your mission and what I see on your front page. "Sustainable crowdfunding" is accurate, but uninspiring. What happened to "gratitude, generosity, and love"? Your blog post sounds like you're trying to remake the world based on those principles. That's a hell of a vision. A crazy vision. The kind of vision that either goes down in flames or inspires thousands. That's the vision that defines what you're doing and why your organisation exists. So why can I find literally no mention of it anywhere on your site?
You mentioned Patreon, so I looked them up. Front and centre on their page: "Be a patron of the arts." There, in one sentence, they have described why someone would care about what they do. A patron of the arts. That's who I could be if I sign up for Patreon. Reviving the noble tradition of patronage. Supporting artists and the arts community. Joining the cultural movement of the future. What a thing to be a part of! What am I a part of with Gittip? Sustainability? You can do so much better.
I suppose my point is that I believe at this point you don't need to improve your product to grow, but rather get more people interested in your product to grow. Like a software project where everyone just writes some code and hopes it links up in the end, I think the way Gittip presents itself has been under-designed, and isn't coherent enough to achieve its goals.
